Seiko Prospex HBB003K1 and HBB004K1 Limited Edition Divers Go on Sale in Asia-Pacific
Seiko’s latest limited-edition Prospex dive watches have officially arrived in select Asia-Pacific markets, giving collectors and diving-watch fans two bold new color options to consider. The Seiko Prospex HBB003K1 and HBB004K1 are now available in Singapore, India, and Thailand, with each model limited to just 2,500 pieces.
The new Prospex models stand out with vibrant yellow and orange dial options, both paired with a black rotating bezel for a sporty, high-contrast look. Designed as capable everyday dive watches, they combine Seiko’s familiar tool-watch practicality with a more eye-catching style aimed at collectors who want something less conventional.
Pricing has now been confirmed across three markets. In Singapore, both models are listed at SGD 899.30. In India, the watches are priced at Rs 75,000. In Thailand, they are available for THB 22,325, which is already around five percent below the listed retail price of THB 23,500.
When local taxes are removed for comparison, Thailand currently appears to offer the lowest effective price at roughly $631. Singapore comes in at about $644 before tax, while India is around $666 before tax. These figures make the Thai listing particularly interesting for buyers tracking regional availability and pricing.
The retail listings also confirm the full reference numbers. While Seiko initially introduced the watches as HBB003 and HBB004, the final retail versions carry the K1 suffix, making them HBB003K1 and HBB004K1.
Both watches feature a 41.7 mm stainless steel case with a thickness of 12.3 mm. They are rated for 200 meters of water resistance, placing them firmly in Seiko’s Prospex diver lineup. The design includes a black rotating bezel, a date window, and Lumibrite on the hands and hour markers for improved visibility in low-light conditions.
Power comes from Seiko’s 4R35 automatic movement, a well-known caliber in the brand’s mechanical lineup. It offers approximately 41 hours of power reserve and supports both automatic winding through wrist movement and manual hand-winding.
The watches are fitted with stainless steel bracelets, reinforcing their durable, everyday-ready character. Another collectible detail is the engraved caseback, with each piece receiving its own unique serial number. Seiko is also shipping both models in a special presentation box, adding to their limited-edition appeal.
Each colorway is limited to 2,500 units, and the release is currently exclusive to the Asia-Pacific region. The models are not intended for the Japanese market, and it remains unclear whether either version will officially reach buyers outside the region.
For Seiko collectors, the Prospex HBB003K1 and HBB004K1 offer a strong mix of limited availability, practical dive-watch specifications, bold color design, and regional exclusivity. With pricing now live in multiple markets and one country already showing a discount, these new Prospex divers could become some of the more closely watched Seiko limited editions of the season.
